Coordination class
async-first pair
China and United States do not share standard 9-to-6 business hours today. Treat this as an async-first corridor and reserve synchronous calls for edge-hour handoffs.
Pair comparison
China vs United States
China is 13.0 hours ahead of United States. They have no overlap in standard 9-to-6 business hours — you'll need edge-hour meetings.
Country comparisons use one representative IANA zone per country, current public-holiday rows, and a same-day business-hour model. Multi-zone countries still need city-level checks before travel or payroll decisions.

Operational read on this pair
DST drift risk
1 sampled shifts / 12mo
United States shifts clocks while China is stable in the sampled reference zone, so recurring meetings can move by one hour for part of the year.
Holiday availability
6 vs 16 listed holidays
China and United States share 2 listed holiday dates in the selected year, so shared shutdown risk is visible before campaign or sprint planning.
Pair workflow examples
What fixed local work times become across the pair
The current offset is enough for today, but the examples below make the page useful for real recurring work: standups, reviews, and end-of-day handoffs anchored to either country. Recheck these around DST transition weeks when either sampled zone shifts.
Anchored in China
- morning standup: 9:00 AM in China is 8:00 PM in United States (previous day).
